New Mercedes Amg GLC 63s Coupé | Silver Color | Rival BMW M X4.
AMG SPEEDSHIFT MCT 9G transmission
A wet start-off clutch replaces the torque converter on the AMG SPEEDSHIFT MCT 9G transmission. It saves weight and optimises response to accelerator pedal commands, especially when accelerating or coming off the power. The multiple downshift function allows more spontaneous bursts of speed, while the double-declutching function in the "Sport" and "Sport+" drive programs makes for an even more emotive driving experience. Defined ignition adjustments also provide faster gear shifts in the other modes. In all modes moving off occurs in first gear in order to always guarantee a dynamic driving experience.
The GLC 63 4MATIC+ SUV and Coupé are shod as standard with 10-spoke light-alloy wheels 8.0 J x 19 (front) and 9.0 J x 19 (rear) painted in titanium grey with a high-sheen finish and with tyres of size 235/55 R 19 (front) and 255/50 R 19 (rear). The dimensions for the GLC 63 S 4MATIC+ SUV and Coupé are 265/45 R 20 (front) and 295/40 R 20 (rear) on 5-twin-spoke light-alloy wheels painted in titanium grey with a high-sheen finish in 9.5 J x 20 (front) and 10.0 J x 20 (rear). There are other, optional wheel/tyre combinations as well as forged wheels, up to sizes of 265/40 R 21 on 9.5 J x 21 on the front axle and 295/35 R 21 on 10.0 J x 21 wheels on the rear axle.
Sensitive and fast: the locking differential
For improved traction and driving dynamics, all models are equipped with an electronically controlled locking differential. This reduces the slip on the inside rear wheel when cornering, without any control intervention in the braking system. The result is that it allows the driver to accelerate out of corners earlier thanks to the improved traction. The vehicle remains more stable when braking from high speed, while the limited-slip differential also improves traction from rest.
The greatest benefit of electronic control is its even more sensitive and even faster adjustment capability in changing driving situations: which pushes the critical threshold higher, making it even easier to drive at the vehicle's limits. The three-stage ESP® with "ESP ON", "ESP SPORT Handling Mode" and "ESP OFF" settings works in perfect unison with the rear-axle limited-slip differential and is optimally tuned to the outstanding dynamics.
S model with dynamic engine mounts as standard
The more powerful GLC 63 4MATIC+ S comes with dynamic engine mounts. These resolve the conflicting aims of comfort and dynamic performance by reducing vibrations in the engine/transmission unit. These dynamic mounts are instantly and variably able to adapt their rigidity to the driving conditions and style of driving. Soft engine mounts improve comfort, as they provide more effective decoupling of noise and vibration. However, handling and agility benefit from a generally stiffer mount set-up. The driver feels more connected to the vehicle when driving dynamically, as there is more feedback and the steering response is more direct. All in all, the driver benefits from a more precise driving sensation.
